Jeison Parra – Brainvitge seminars

04/05/2020 · 12:00 - 13:30

From Cognition and Brain Plasticity Unit, Learning from Reward Group
will present the talk titled

Temporal Difference, Pseudo-rewards, and sub-optimal decision making

Abstract

Actions are organised in successive linked steps and their completion is motivated by goal acquisition. This behavioural structure generates hierarchies that set up sub-goals for each level as a prerequisite to getting benefits. There is evidence that pseudo-rewards are tracked due to sub-goal attain. The assumption of learning suggests the existence of prediction errors (RPE) that explain the approaching behaviour to sub-goals. Also, research has shown that RPE are related to similar brain areas than pseudo reward prediction errors (PRPE). In the present study, 226 university students participated through two behavioural (n=176) and one EEG experiments (n=24). The task consisted of two options, presented as two figures in two steps. The aim of the study was to test whether Pseudo rewards are capable of bias choice behaviour or not.
